Process for making goat denim line simulated upper leather

The invention aims to provide a process for making goat denim line simulated upper leather. The process specifically comprises the following flows in sequence: soaking, fleshing, painting with lime, dehairing, liming, deliming, softening, pickling, tanning, blue rawhide lot grouping, wringing, shaving, re-tanning and dyeing, secondary wringing, vacuumizing, hang airing, water returning, vibrating staking, setting out, toggling, trimming, buffing and finishing. The process has the beneficial effects that proper and moderate liming aids are selected to promote the limed hide to swell moderately, so that the tear strength of the hide is improved, the growth lines and back lines of the rawhide are completely unfolded and the grain side is flat and fine, thus increasing the leather yield; and the location difference of the hide body is reduced, the plumpness of the whole hide is improved and the hide body can be moistened.
